Provided is a charging roller that can achieve excellent image quality and prevent detachment of particles in its surface layer. A charging rollercomprises a shaftand, on an outer circumferential side of the shaft, at least a base layerand a surface layer, wherein the surface layercontains a binder resinand particles, and the particlescontain 50 mass % or more of a same component A as at least one selected from components constituting the binder resin, and a content of the particles in the surface layer is 30 parts to 120 parts by mass with respect to 100 parts by mass of the binder resin.

Charging roller and image forming apparatus

A charging roller comprises a shaft member, a base layer located outside in the radial direction of the shaft member, and a surface layer located outside in the radial direction of the base layer and forming a surface. The surface layer includes particles, and the ratio of the total area of the particles exposed from the surface of the surface layer in a planar view seen from the radial direction of the charging roller, with respect to the area of the surface of the surface layer is more than 60%.

A navigation device includes a road periphery display change unitthat selects a road R which connects to, intersects with, or is adjacent to a guidance route/a travel plan routefrom a map database, and displays the road in a high contrast on the inside of a predetermined distance from the guidance route/the travel plan route, displays the road in a low contrast on the outside of the predetermined distance, and displays the road by changing continuously or stepwise a gradation in an intermediate region between the inside and the outside.

Navigation device

Disclosed is a navigation device including a guidance route calculation unitfor calculating a guidance route by using point information about a destination, point information about a current position, and map information, a guidance map generating unitfor generating a guidance route map by using the calculated guidance route and the map information, a guidance route surrounding facility icon arrangement unitfor extracting a facility icon required for the calculated guidance route according to a facility icon extraction rule, and for determining an offset arrangement position of this facility icon, and a display unitfor attaching the facility icon at the above-mentioned determined offset arrangement position on the above-mentioned guidance route map to display the facility icon.

In order to reduce the computational burden required for scanning and to enhance the recognition accuracy, an image recognition device is configured so that a scanning pattern recording unit that records a plurality of scanning patterns for directing how to scan recognition areas of predetermined size in the image data is included, and different scanning patterns for successive frames are read out from the scanning pattern recording unit and applied to scan the recognition areas.
